Doesn't this add a lot of noise to the logs, since this may happen  
quite frequently?  If you feel it should be, I don't mind it being  
switched to INFO.

I thought this in fact is useful for debugging, to make sure proper  
configurations have been read, etc.  And since it only happens once  
as the cache starts, I don't see this as very noisy.

As with my argument on 1), this could be noisy since it happens  
whenever there is a view change.  Again though, if you feel this is  
useful as INFO, I'm ok with it.

I would have thought some of these are useful for sysadmins - to  
check that the buddies are being selected according to the rules they  
define (around colocation, buddy pools, etc.).
